Filed: 2002-09-20
Abstract: <P>PROBLEM TO BE SOLVED: To provide an encoding method and a decoding method for contents, capable of preventing encoded contents obtained by encoding contents data from being decoded, when the encoded contents are decoded.  <P>SOLUTION: Contents data is reversibly compressed and encoded, to obtain reversibly compressed contents, and an encoded environment parameter encoded is read and recorded on a recording medium together with a decoded program. Once the decoded program is started in a computer (S11), the encoded environment parameter is read from the recording medium (S12), and a decoded environment parameter is read from the computer (S13). When both the environment parameters are compared (S14), and possibility of illegal duplication is low, the reversible compressed contents are decoded (S15). When the possibility of the illegal duplication is high and an input CPU-ID does match (S17), it is decided as being illegal duplication, and the decoding of the reversibly compressed contents will not be allowed (S19).  <P>COPYRIGHT: (C)2004,JPO

The amount of shift within the window ranges when the maximum correlation value is obtained is computed. The distance to the object of distance measurement is computed on the basis of the amount of shift. The distance measuring device detects a plurality of correlation extremal values from the computed correlation values, and interpolates the extremal values to compute a plurality of interpolation correlation extremal values. A first interpolation correlation extremal value which provides the maximum correlation among the plurality of interpolation correlation extremal values is detected as the maximum correlation value.  <P>COPYRIGHT: (C)2004,JPO

Abstract: <P>PROBLEM TO BE SOLVED: To provide a semiconductor device having a capacitor in which high reliability is provided by preventing a dielectric film from being electrostatically destroyed by a plasma when forming a contact hole, and to provide a manufacturing method thereof.  <P>SOLUTION: Until forming upper electrode wiring and a lower electrode wiring, a first conductive film 5 which becomes an upper electrode and a lower electrode 3 are electrically short-circuited.

Therefore, since a current which flows from the first conductive film 5 which becomes the upper electrode to the lower electrode 3 via a dielectric film 4 is reduced, the electrostatic destruction of the dielectric film 4 is prevented and the semiconductor device having the reliable capacitor is manufactured.  <P>COPYRIGHT: (C)2004,JPO

Filed: 2002-10-17
Abstract: <P>PROBLEM TO BE SOLVED: To provide an apparatus and a method for retransmitting a packet in a mobile communication system.  <P>SOLUTION: When there is a request for retransmission from a receiver a transmitter rearranges coded bits and maps the rearranged bits to modulation symbols. The modulation symbols of a retransmission are transmitted with different reliabilities from those of an initial transmission. The receiver demodulates received data and outputs the coded bits and afterwards, when the coded bits are retransmitted for the same data, the coded bits are rearranged to an original constitution and decoded. Thus, bit error rates for initial transmission and for retransmission are averaged and decoding performance in a receiving terminal is improved.  <P>COPYRIGHT: (C)2003,JPO
